This paper demonstrates the bandpass (BP) negative group delay (NGD) function on a passive RLC-parallel lumped network at Very High Frequencies (VHF). After the topological description of the RLC cell, the BP NGD analysis is introduced. The NGD circu

Flat Hyperbolic Centro-affine Tchebychev Hypersurfaces of $$\mathbb {R}^{4}$$

Autor: Lucius Ramifidisoa, Sebastien Lallechere, Blaise Ravelo

Publikováno v: Results in Mathematics. 76

We study centro-affine Tchebychev hyperbolic hypersurfaces M in $$\mathbb {R}^{4}$$ , which satisfy the following conditions: for all $$X,Y,Z \in T_{p}M$$

Journal of Molecular Liquids, Elsevier, 2019, 277, pp.1036-1046. ⟨10.1016/j.molliq.2018.12.059⟩

The stability of shear-thinning fluid down an inclined plane is investigated theoretically with application to process engineering (coating process) and natural hazards as well (debris flow impact). The power-law model is used to describe the fluid r
